    10 kg block sliding on floor with friction: find KE, PE and speed after 2 m

    Yes, we found the friction force. Now how do we use that amount to figure out the energies and the final velocity?

    10 kg block sliding on floor with friction: find KE, PE and speed after 2 m

    Homework Statement Initially, a 10 kg block is sliding along the floor at a speed of 5 m/x. The coefficient of friction between the block and the floor is 0.5. What are the KE, PE and total energies of the block after sliding 2.0 m? What is the block's speed after sliding 2.0 m? I...
